Add a figure to illustrate JSON-based syntax of MBS User Service Announcement

[rjb1000]

Context

TS 26.517 specifies two alternative syntaxes for the MBS User Service Announcement:

• An XML-based syntax specified in clause A.1 is specified for use in the User Service advertisement procedure. This maintains a degree of backwards compatibility with the MBMS User Service Announcement syntax. The announcement is provided using up to three separate documents, each with its own XML schema:
  1. MBS User Service Description schema (clause A.1.1).
  2. Object Repair Parameters schema (clause A.1.2), optionally referenced by (i).
  3. Schedule Description schema (clause A.1.3), optionally referenced by (ii).
• The (preferred) JSON-based syntax specified in clause A.2 is specified for use in the User Service advertisement procedure. For one of the advertisement modes, it needs to be handed back to the MBS Application Provider via the Nmbsf_MBSUserDataIngestSession service, and JSON syntax is strongly preferred there. In this case, all of the MBS User Service Announcement is encapsulated in a single JSON document.

Problem description

Figure 5.1-1 in TS 26.517 illustrates the division of the MBS User Service Announcement into three XML documents.

There is no corresponding figure to illustrate the single combined JSON document.

Suggested solution

Produce a figure 5.1-2 showing the arrangement for the combined JSON syntax.
